Verdict

Nextcloud and Syncthing solve different problems. Nextcloud is a cloud server you log into from any browser, with share links, calendars and office editing. Syncthing is peer-to-peer folder sync between devices you own, with no central server or web file access, which makes it simpler and very private but not a Dropbox-style sharing platform.

FAQ

Nextcloud vs Syncthing: FAQ

Still curious? Email info@appsgit.com.

Can Syncthing replace Nextcloud?

Only for file sync between your own devices. Syncthing has no web interface for files, no public share links and no calendar or contacts, which Nextcloud provides.

Can I use Nextcloud and Syncthing together?

Yes. Some people use Syncthing to sync folders between machines and Nextcloud to share and access those files from the web, though you should avoid two tools writing to the same folder at once.

Does Syncthing need a server?

No. Devices connect directly to each other; public relay and discovery servers only help them find each other and never see unencrypted data.

Syncthing has 89,175 GitHub stars against 37,003 for Nextcloud. Over the last twelve months Nextcloud received 7,289 commits and Syncthing received 223, so Nextcloud is the more actively developed of the two right now. Stars measure interest, not fit, so weigh them against the differences above.
